SlCKLE-GRINDER.

SPECIFICATION forming part of Letters Patent No. 448,4:73, dated March 17, 1891.

Application filed October 27,1890. Serial No. 369,473. (Model) To all whom it may concern.-

Be it known that I, GEORGE J. OLINE, a c tizen of the United States of America, residing at Goshen, in the county of Elkhart and State of Indiana, have invented certain newand usefulImprovementsinSickle-Grinders, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to certain improvements in grinding-machines; and it consists in the novel construction and combination of parts, as hereinafter explained, and pointed out in the claim.

In the accompanying drawings, Figure l is a perspective view of my improved grinder. Fig. 2 is a broken sectional elevation of the same, and Fig. 3 is a detail plan View showing more fully the knifetable.

111 the embodiment of my invention I suitably secure or bolt upon a support or base A by bolts and nuts to a U-standard 13, between the upper free ends of which is arranged a bearing-block (1, whose halves or sections (1 d are clamped by bolts and nuts upon a j ournal or shaft 1), itself journaled or hearing in said ends of said standard. One end of the shaft or journal I) is angular and adapted to permit of the application thereto of a handlever O for the manipulation of said bearingblock together with the grinder (presently described) in adjusting the latter to theknife for grinding or sharpening the knife.

6 is the grinder, of emery or other suitable material, preferably in the form of two truncated cones placed base to base and having its shaft 6' hung or journaled in the lower free ends of the arms of a bifurcated bracket or hanger g, as at e", the upper ends of said arms being themselves hung or pivoted upon a journal or shaft 7t, journaled in the halves or sections of the bearing-block at the outer end of the latter.

Upon one end of the shaft or journal his carried or supported the large toothed or cogged Wheel it, having a crank or handle 7; for its rotation and geared to a pinion secured upon the shaft 6' of the grinder e for the rotation of the latter in effecting the grinding or sharpening of the knife.

The grinder e is yieldingly or elastically held to its work for its better operation in sharpening or grinding the knife by means of the spring D, one end of which is connected,

as at Z, to the bracket or hanger g and having its other end connected, as at l, to either of two hooks m, secured to the base or support A, permitting of varying the tension of the spring or compensating wear therof.

Projecting from the forward side of the standard 13 a U or bail shaped supportf, to which is secured a cushion f, against which bracket or hanger g normally rests.

E is the stepped table, secured upon the base or support A for supporting the knife while being ground, having the upper surface of its upper step inclined outward and downward to properly dispose the knife to the grinder, the inner edge of said table having a recess 6 corresponding with the contour and adapted to receive the salient edge of the grinder in order to bring it (the grinder) in engagement with the knife.

I is a cam-lever held upon the lower step of the table E by a bolt and nutf and adapted to engage and clamp the knife down upon the table, as shown.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

The grindingmachine having journaled upon a shaft or journal supported between the upper ends of a standard a bearing-block whose free end bears a journal or shaft carrying-a handled wheel, in combination with a bracket or hanger carrying the grinder,wl1ose shaft carries a pinion geared to said wheel, and the spring connected to said bracket and to the base of the machine, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE J. CLINE.
